2 Claims.

This invention relates to binoculars and especially to a light weighttype of construction, Which may be worn conveniently with or withoutspectacles, and has for its main object the provision of improvements tomy co-pending application Serial No. 274,204.

One object of the invention is the provision of a collapsible type ofbinocular structure which is provided with positive means for stoppingand holding the lens in focal location simultaneously with the openingof the temple bar members when the same are set to nt the head of aperson intending to use them.

Another object of the invention is toprovide a single lens structurewhich will permit vision thru one common focal point or focal center ofthe said lens, and which will permit a user to look therethru with botheyes at the same time having no interfering structure in between such asis customarily used in binocular structures thus presenting a true andclear view.l

Another object of the invention is the provision of a lens mountingmember which permits of ready accessibility for replacement andinterchangeability of lenses. I

Other objects of the invention will become apparent When referring tothe accompanying drawing, and the following description, wherein likesymbols are used to designate like parts and in which;

Fig. 1 is an isometric View showing diagrammatically the eyes of aperson wearing my device, who may also wear glasses at the time, showingalso that the wearing of glasses, in no way interferes or impedes thewearing, operation, or use of my invention.

Fig. 2 is a top View looking at my invention when in collapsed form, andshowing also in dotted arrangement the open position of the frame workcomprising my invention.

Fig. 3 is a front View of the View shown in Figure 2.

Fig. 4 is a staggered cross-sectional view on the line 4 4 of Figure 2.

Fig. 5 is a cross-sectional view on the line 5 5 of Figure 2.

Fig. 6 is a slightly modified ers in front elevation.

Fig. 7 is a top view of the ure 6.

Referring to the various views it will be noted in Figure 1 that astandard pair of spectacles is generally designated by the numeral 8,having a bridge member designated by the numeral form of lens holdviewshown in Fig- I2, connected to the Vsuitably counter-bored and templebar members designated by the numeral 9.

My invention as described in my co-pending application is similarlyconstructed and has a bridge member designated by the numeral Il, havinga section designated by the numeral 29 to nt the nose of a wearerconveniently, and is provided with temple bar members designated by thenumeral 2| This view is schematic and the lens is shown in schematicrelationship with the remainder of the structure; the main purpose ofthis View being to show that a wearer who must use spectacles forcorrective vision, will nd that the device will readily fit alongside ofsuch spectacles .and in no Way interfere with or impede the eflicientuse of my invention.

Referring to Figure 2, and as described in my yco-pending application, Iprovide a bridge member generally designated by the numeral however inthis case I provide two extensions designated by the numeral I 3, and byreferring to Figure 4, I show the means utilized for stopping the lensin focal position when the temple bars 2| are opened as indicated by thedotted lines ready to be placed on the head of a user, or a persondesiring to inspect certain specimens With the binoculars comprising myinvention.

The stopping means consists of a stopping pin member designated by thenumeral 2|! which may be driven into the portion I3 of the member Il, orthe portion I3 being of sheet metal may have formed integrally therewitha lug portion for stopping the temple bar designated by the numeral 2|.

The temple bar is provided with a flat swaged portion designated by thenumeral |5 which is adapted to ride on the bearing washer designated bythe numeral 38. The assembly is held in place by virtue of a fillisterhead screw designated by the numeral'l the portion I3 being to receivethe same, and having a body portion designated by the numeral I1, and areduced threaded portion designated by the numeral I 8 adapted toreceive the nut designated by the numeral I9.

The length of the body portion designated I 1 is approximately tenthousandths of an inch more than the combined dimensions of the depth ofthe bore in the portion I3, the thickness of the washer 33, and thethickness of the swaged portion I5, in order to allow a nice freeworking fit of the member 2| when assembled in the manner heretoforepointed out.

The members 2| have extensions I4 which are intermediate linksdesignated Y mately in the shape as shown,

" an observer or inspector.

The Vlens holder is primarily maderapproxiby thev numeral 22 beingprovided with reduced upper portions in'order to lend symmetry anddesign to the construction, and is provided with two .curved endportions meral 30 adapted to receive the lens designated 24 which isshaped approximately as indicated." Any type lens may be utilized andhence the holders may be shapedaccordingly in order to fit therespective lenses that are may beeitherl permanently attached orinterchahgeably as will hereinafter be explained.

The lens is held in place-by slipping it into the channel portionsdesignated 30, and is -held from dropping thru by the small ledgesdesignated -by the numeral-23.- l Y The vmembers-2iy are permitted toswivel in the assembly-at the point where they are attached to the lensAholder member 22 by virtue of the backing plate designated by thenumeral 32; the

and is designatedv to'be used `which* not obstructed byV any portion ofmy device. Thus it can be seen that my invention holds the lens in themost ideal position for observation and use.

Inasmuch as my device will be used by jewelers, optometrists,physicians, stamp collectors, examiners, and many others, it will beadvantageous to use lenses of different focal ranges and magnification.When the device is not in use, it may be conveniently carried about,because it may be collapsed as shown in Figures 2 and 3.

Altho I have described the improvement in my invention, I feel thatthere is possibility of further modification and improvement,'mypresentation to be considered merely as a preferred form,

VVand the right is reserved to all improvements and -lmodiiicationscoming within the scope of my indesignated by the nu-VV .y

' means, intermediate link members pivotally se-- said backing -platebeing indented as indicated at 33 Whereas lthe plate 22 is indented insemi-circular fashion as indicated'at 3| thus providing suitablebeari-ng surface and retaining means for the portions --21 of theintermediate linkage 26. The back-ing `plate 32 is secured to the member22 by pins or rivets designated 'An improved Vform or slightmodification of the lens-holder is -shown in Figures 6 and 'l whereinthe lens holder generally designated 22 has one vside removedtherefromand in place thereof a separate piece designated by the,numeral 34 is provided which has an arcuate or curved recess designatedby the numeral 31, anda ledge portion designated 'by the numeral 35. AThis member` Sli is swivelably attached at the point Y:it and may beswung out -as indicated by the dotted line when it is desired tolexchange lenses, insert a lens, or remove a lens.

' The device is iirst set for use by opening the same as indicated bydotted lines (Figure 2), this places the lens in position forobservation and inspection. It can be seen according to Figure 2 that anobserver amine specimens requiringy have free use ofthe hands. VThelines of vision are indicated when examining a specimen bythe convergingarrows passing thru the center of the binocular lens; whereenlargement,and yet Vas rif the observer wishes to lookup from his wearing myinvention mayexvention, and the purview of the foregoing description; myinvention being limited only by the appended claims.
